Collective administration of literary works

Reproduction rights organizations, which administer reproduction copyrights collectively, are one of the major implementation mechanisms for copyright law, on both a national and an international level. The operation of RROs is described, with examples from Norway, Germany, the United Kingdom, and the United States. The International Federation of Reproduction Rights is discussed, and future plans for licensing databases are summarized. This article was adapted from a presentation to Latin American Copyright Specialists at the Library of Congress, Washington, D.C., May 1991, which was sponsored by the International Copyright Institute of the U.S. Copyright Office and the World Intellectual Property Organization.     

Stimulus discriminability,contingency discriminability,and schedule performance

A detection-theory model to describe the effects of varying stimulus disparity on switching-key concurrent variable-interval schedule performance (Miller, Saunders, & Bourland, 1980) is presented. It describes the available data on stimulus disparity well. Using the additional notion of contingency discriminability, the model is then developed into an account of schedule and stimulus control that is both wider in application and conceptually clearer than the generalized matching law. A basic assumption of the new model is that subjects may not perfectly discriminate that a reinforcer followed a response of one class versus that of another, and this ability is measured as reinforcer-contingency discriminability, d_r. This idea is then applied to performance in signal-detection procedures, both with and without error reinforcement, to multiple-schedule performance, and to single-schedule performance. The model fitted the data well, and it thus constitutes a coherent and viable alternative to the generalized matching law in the procedures and conditions in which the latter has been shown to apply.     

Criticality in international higher education research: a critical discourse analysis of higher education journals

The current study utilizes the theory of planned behavior (Ajzen Organizational Behavior and Human Decision Processes, 50, 179–211 Ajzen 1991) to examine an instructor confirmation-interaction model in the instructional communication context to discover a means by which instructors might cultivate positive student attitudes and increase beliefs that interactions with instructors would be beneficial in the future. Specifically, the model examines how teacher confirmation (Ellis 2000) influences students’ behavioral intention to communicate with instructors. Surveys were distributed to 343 college students (41.7% male and 58.1% female) in a basic communication course. Results were primarily consistent with the proposed model; teacher confirmation was significantly related to attitudes toward communicating with an instructor, subjective norms, and perceived behavioral control. Subjective norms and perceived behavioral control were also positively related to students’ behavioral intention to communicate with the instructor. However, results reveal attitudes toward communicating do not predict students’ behavioral intention to communicate with instructors. It is recommended that future models examine a more contemporary, hi-tech representation of attitude toward student-instructor interactions as it may produce a significant association with students’ behavioral intent to communicate with them. The study concludes with theoretical and practical implications to examine student classroom communication via the confirmation-interaction model and the theory of planned behavior.     

A Longitudinal Study of Two Early Intervention Strategies: Project CARE

65 families with children at risk for cognitive difficulties were randomly assigned at the time of the child's birth to 1 of 3 groups, 2 intervention and 1 control. For the most intensive intervention group, family education was combined with a center-based educational day-care program; the less intensive intervention group received the home-based family education program only. To assess the cognitive performance of children, The Bayley Scales of Infant Development were administered at 6, 12, and 18 months; the Stanford-Binet Intelligence Test at 24, 36, and 48 months; and the McCarthy Scales of Children's Abilities at 30, 42, and 54 months. On each test after the 6-month assessment, scores of children in the educational day-care plus family support group were greater than those in the other 2 groups. No cognitive intervention effects were obtained for the family education group. Group effects were not obtained for measures of either the quality of the home environment or parent attention.     

Characteristics of male disciplinary students at a catholic university

This study examined selected measures of demographic, social, and academic characteristics for a male disciplinary population at Villanova University, to determine the usefulness of these variables in predicting membership in a disciplinary group from one graduating class to the next. The step wise multiple regression analysis showed that the predictability of these measures for this population was minimal.
